The odds of being able to talk to an actual Engineer from any of the gasket/seal companies is about as likely as calling ExxonMobil and speaking to a lubrication Engineer.
You talk to a "Customer Service Representative" that will tell you all kinds of exciting stuff (I cite the varied responses we've got from the oil companies over the years that often clash with other responses from the same company.... just from a different rep as an example here) that may or may not reflect the position of the company they represent.
I would LOVE to see an actual statement, authorized by a company like Felpro, on this topic. Because it completely contradicts the official statements made by the oil companies as well as the experience of those who have actually done what is being argued against here and observed no issues.
In my time, I've built... oh, I don't know. At least a thousand engines. I never, ever, ever, even at the peak of the PAO-synthetic debacle, worried about some obscure combination of gasket and oil that would magically cause a leak. In my opinion, engines that leaked with early synthetics were already leaking, they just leaked MORE once their seals "un-swelled," which has always been my understanding of what was going on with the PAO's.
Hat's off to you sir!
That's a heck of a lot of experience! You sound like an engine builder I know
There's not as much variety as you might think, though. I probably did 75 a year of just one particular type back in the mid-90's. Good pay, but I had to get out of it.
